Abstract (en)
Compositions suitable for borehole uses comprise an inorganic part, which is swellable in water, which is dispersed within a polymer that may or may not be swellable in water and/or non-aqueous fluids. The compositions can be capable of swelling at temperatures over 300°C, and provide significant advantages over salts and swelling clays. Also disclosed are the methods used to make these compositions, as well as the applications of these compositions.
